About Thanks.io
Through Operate As, your agent, n8n workflow or code works in Thanks.io with your client's own access. Your client pastes their API key from Thanks.io once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Thanks.io's API through the request tool, with the client's access attached.
